On the 70th anniversary of the liberation of Auschwitz, a one-hour documentary, “Voices of Auschwitz,” airing Jan. 28, (locally 7 p.m. Wednesday on CNN), offers the inspiration of survivors and honors those who died in the Holocaust.

Four remarkable survivors tell their stories on camera, reliving memories of torture and loss and recalling the moment of liberation. Archival footage and current views of the camp combine in a moving film that finds light and life in a horrifically dark subject.

Wolf Blitzer (whose paternal grandparents died at Auschwitz) also talks to Steven Spielberg about the importance of never forgetting. Spielberg recalls finding “his calling” beyond the movies during the filming of “Schindler’s List.” That led him to found the University of Southern California Shoah Foundation which gathers video testimonials of survivors of the Holocaust. More than 53,000 accounts have been recorded in the archive, but, he says, “there are not going to be enough survivors for the 75th” anniversary.

The four featured here:
Eva Kor, who with her twin sister Miriam endured Mengele’s twin experiments. She determined early on, she tells Blitzer, “I was not going to perish here in Auschwitz.” Rising above anger and fear is “the ultimate victory,” she says.

Martin Greenfield, who survived the freezing death march by wearing layers of discarded Gestapo uniform shirts he obtained by working as a tailor in Auschwitz, says on camera, “I survived Auschwitz and I’m happy about it.” He is now a successful maker of hand-tailored suits.

Renee Firestone, who survived by using her skills as an aspiring designer, eloquently describes the experience of being shipped to Auschwitz in cattlecars for three days with 120 people and no water. She doesn’t seek revenge. Her revenge is that she lived, she says.

Anita Lasker-Wallfisch survived by playing the cello in a makeshift orchestra at Auschwitz, and went on to become a founding member of the English Chamber Orchestra. “I never accepted that anybody had the right to murder me because I happened to be Jewish,” she says.

Joanne Ostrow has been watching TV since before "reality" required quotation marks. "Hill Street Blues" was life-changing. If Dickens, Twain or Agatha Christie were alive today, they'd be writing for television. And proud of it.
